javascript - How to replace values dynamically in Angular? -

my url structure:

/json/feed?car=${cars}&colour=${color}&model=vw 

i want replace in ${} javascript var's have available (var cars, var colors, etc.), not sure how can angular.

would like:

$scope.newstring = oldstring.replace("${cars}","cars"); 

work ok, or there %s way of doing javascript ? better way angular?

replace variable instead of string.

$scope.newstring = oldstring.replace("${cars}",$scope.cars);

please take @ plunkr reference.

you can chain .replace's.

$scope.new = old.replace('${cars}', $scope.car).replace('${color}', $scope.color).replace('${model}', $scope.model);
